I-Betaineisetyenziswa njengento etsala ukutya kwizilwanyana zasemanzini.

Ngokutsho kwemithombo yangaphandle, ukongeza i-0.5% ukuya kwi-1.5% ye-betaine ekutyeni kweentlanzi kunefuthe elinamandla lokuvuselela kwiimvakalelo zokuhombisa nezokutya zezilwanyana ezihlala emanzini ezifana neentlanzi kunye nee-shrimp. Inomtsalane onamandla wokutya, iphucula ukutyeba kokutya, inciphisa ixesha lokutya, ikhuthaza ukugaya nokufunxa, ikhawulezisa ukukhula kweentlanzi kunye nee-shrimp, kwaye ithintela ungcoliseko lwamanzi olubangelwa kukungcola kokutya.

I-Betainesisithako esikhuselayo sokuguquguquka koxinzelelo lwe-osmotic kwaye singasebenza njengomkhuseli we-osmotic weseli. Sinokuphucula ukunyamezela kweeseli zebhayoloji kwimbalela, ukufuma okuphezulu, ityuwa ephezulu, kunye neendawo eziphezulu ze-osmotic, sithintele ukulahleka kwamanzi eseli kunye nokungena kwetyuwa, siphucule umsebenzi wepompo ye-Na K yee-membranes zeseli, sizinzise umsebenzi we-enzyme kunye nomsebenzi we-macromolecule yebhayoloji, silawule uxinzelelo lwe-osmotic lweseli yezicubu kunye nokulinganisela kwe-ion, sigcine umsebenzi wokufunxa izondlo, kwaye siphucule iintlanzi Xa uxinzelelo lwe-osmotic lwee-shrimp kunye nezinye izinto eziphilayo zidlula kutshintsho olukhulu, ukunyamezela kwazo kuyanda kwaye izinga lokusinda kwazo liyanda.

 I-BetaineIngabonelela nangamaqela e-methyl emzimbeni, kwaye ukusebenza kwayo ekuboneleleni ngamaqela e-methyl kuphindwe ka-2.3 kune-choline chloride, nto leyo eyenza ukuba ibe ngumnikeli we-methyl osebenza kakuhle. I-Betaine inokuphucula inkqubo ye-oxidation ye-fatty acids kwi-cell mitochondria, inyuse kakhulu umxholo we-long-chain acyl carnitine kunye nomlinganiselo we-long-chain acyl carnitine ukuya kwi-carnitine ekhululekileyo kwimisipha nesibindi, ikhuthaze ukubola kwamafutha, inciphise ukugcinwa kwamafutha kwisibindi nasemzimbeni, ikhuthaze ukwenziwa kweproteni, isasaze kwakhona amafutha e-carcass, kwaye inciphise izinga lokwenzeka kwesibindi esinamafutha.
